of obstruction.
•Connect the yellow-green protection grounding cable before power-on.
•Make sure that the operating voltage is in the range labeled on the power supply of the switch.
•To avoid electrical shocks, do not open the chassis when the switch is operating or when the
switch is just powered off.
•When replacing FRUs, wear an ESD wrist strap to avoid damaging the units.
Examining the installation site
The switch must be used indoors. You can mount your switch in a rack or on a workbench, but make
sure:

3
•Adequate clearance is reserved at the air inlet and outlet vents for ventilation.
•The rack or workbench has a good ventilation system.
•The rack is sturdy enough to support the switch and its accessories.
•The rack or workbench is reliably grounded.
To ensure normal operation and long service life of your switch, install it in an environment that meets
the requirements described in the following subsections.
Temperature/humidity
Maintain appropriate temperature and humidity in the equipment room.
•Lasting high relative humidity can cause poor insulation, electricity leakage, mechanical
property change of materials, and metal corrosion.
•Lasting low relative humidity can cause washer contraction and ESD and cause problems
including loose mounting screws and circuit failure.
•High temperature can accelerate the aging of insulation materials and significantly lower the
reliability and lifespan of the switch.
For the temperature and humidity requirements of different switch models, see "Environmental
specifications."
Cleanliness
Dust buildup on the chassis might result in electrostatic adsorption, which causes poor contact of
metal components and contact points, especially when indoor relative humidity is low. In the worst
case, electrostatic adsorption can cause communication failure.
Table 3 Dust concentration limit in the equipment room
Substance Concentration limit (particles/m³)
Dust ≤3 x 104 (no visible dust on the tabletop over three days)
NOTE:
Dust diameter ≥5 μm
The equipment room must also meet strict limits on salts, acids, and sulfides to eliminate corrosion
and premature aging of components, as shown in Table 4.
Table 4 Harmful gas limits in the equipment room

SO20.2
H2S 0.006
NH30.05
Cl20.01
EMI
All electromagnetic interference (EMI) sources, from outside or inside of the switch and application
system, adversely affect the switch in the following ways:
•A conduction pattern of capacitance coupling.

4
•Inductance coupling.
•Electromagnetic wave radiation.
•Common impedance (including the grounding system) coupling.
To prevent EMI, use the following guidelines:
•If AC power is used, use a single-phase three-wire power receptacle with protection earth (PE)
to filter interference from the power grid.
•Keep the switch far away from radio transmitting stations, radar stations, and high-frequency
devices.
•Use electromagnetic shielding, for example, shielded interface cables, when necessary.
Laser safety
WARNING!
Do not stare into any fiber port when the switch has power. The laser light emitted from the optical
fiber might hurt your eyes.
The HPE 5800 and HPE 5820X switches are Class 1 laser devices.
Installation tools
•Flat-blade screwdriver
•Phillips screwdriver
•ESD wrist strap
All these installation tools are user supplied.

NOTE:
If a rack shelf is available, you can put the switch on the rack shelf, slide the switch to an appropriate
location, and attach the switch to the rack with the mounting brackets.
Attaching the mounting brackets, chassis rails, and
grounding cable to the chassis (5800AF-48G/5820AF-24XG)
The 5800AF-48G and 5820AF-24XG switches have one front mounting position (near the network
ports) and one rear mounting position (near the power supplies). The switches also have one
primary grounding point (with a grounding sign) and two auxiliary grounding points. Use the primary
grounding point whenever possible. If the primary grounding point fails or is not suitable for the
installation site, use one of the auxiliary grounding points.

10

(3) Primary grounding point (4) Auxiliary grounding point 1
(5) Front mounting position
Attaching the mounting brackets and chassis rails to the chassis
1. Align the mounting brackets with the screw holes in the rear mounting position (see Figure 9) or
front mounting position (see Figure 10).
2. Use M4 screws (supplied with the switch) to attach the mounting brackets to the chassis.
3. Align the chassis rails with the rail mounting holes in the chassis:
{If the mounting brackets are in the rear mounting position, align the chassis rails with the
screw holes at the front of the side panels (see Figure 9).
{If the mounting brackets are in the front mounting position, align the chassis rails with the
screw holes at the rear of the side panels (see Figure 10).
4. Use M4 screws (supplied with the switch) to attach the chassis rails to the chassis.
NOTE:
Secure the mounting brackets and chassis rails to both sides of the chassis in the same way.
Connecting the grounding cable to the chassis
CAUTION:
The primary grounding point and auxiliary grounding point 1 are located on the left side panel. If you
use one of these grounding points, you must connect the grounding cable to the grounding point
before you mount the switch in the rack.
NOTE:
•As a best practice, use the primary grounding point or auxiliary grounding point 1 because the
grounding cable and grounding screw that come with the switch are suitable only for these two
grounding points.
•To use auxiliary grounding point 2, you must prepare a grounding cable yourself.
To connect the grounding cable to a chassis grounding point, for example, the primary grounding
point:
1. Choose a grounding point.

11
2. Unpack the grounding cable and grounding screws.
You can use the cable and screws shipped with the switch only for connecting to the primary
grounding point or auxiliary grounding point 1.
3. Align the two-hole grounding lug at one end of the cable with the grounding holes of the
grounding point, insert the grounding screws into the holes, and tighten the screws with a
screwdriver to attach the grounding lug to the chassis, as shown in Figure 9.

12
Attaching the mounting brackets to the chassis (for all the
switches except the 5800AF-48G/5820AF-24XG)
All 5800 and 5820X switches except the 5800AF-48G and the 5820AF-24XG have three mounting
positions: one front mounting position (near the network ports), one mid-mounting position, and one
rear mounting position (near the power supplies).
To attach the mounting brackets in one of these positions:
1. Align one mounting bracket with the screw holes in the front-mounting position (Figure 11),
mid-mounting position (Figure 12), or the rear-mounting position (Figure 13).
These figures show attaching a 1U bracket to a 1U switch chassis. To attach a 2U bracket to a
2U switch chassis, see Figure 14.
2. Use M4 screws (supplied with the switch) to attach the mounting bracket to the chassis.
3. Repeat the proceeding steps to attach the other mounting bracket to the chassis.

Figure 14 2U bracket front mounting position
NOTE:
•Installing the 2U mounting brackets in the rear mounting position is the same as installing the
brackets in the front mounting position.
•To install the 2U mounting brackets in the mid-mounting position of a 2U switch chassis, first use
a screwdriver to loosen the three captive screws and separate the mounting brackets from the
cable management brackets (see Figure 15).

Rack-mounting a 5800AF-48G/5820AF-24XG switch
Attaching the slide rails to the rack
You must install slide rails for rack-mounting a 5800AF-48G or 5820AF-24XG switch.
To attach the slide rails to the rack:
1. Identify the rack attachment position for the slide rails.
2. Install cage nuts (user-supplied) in the mounting holes in the rack posts.
3. Align the screw holes in one slide rail with the cage nuts in the rack post on one side, and use
screws (user supplied) to attach the slide rail to the rack, as shown in Figure 16.
4. Repeat the preceding step to attach the other slide rail to the rack post on the other side.
Keep the two slide rails at the same height so the slide rails can attach into the chassis rails.

14
Figure 16 Installing the slide rails
Mounting the switch in the rack
This task requires two people. To mount the switch in the rack:
1. Wear an ESD wrist strap and make sure it makes good skin contact and is correctly grounded.
2. Verify that the mounting brackets and chassis rails have been securely attached on the two
sides of the switch.
3. Verify that the slide rails have been correctly attached to the rear rack posts.
4. Install cage nuts (user-supplied) to the front rack posts and make sure they are at the same
level as the slide rails.
5. Supporting the bottom of the switch, align the chassis rails with the slide rails on the rack posts,
as shown in Figure 17. Work with another person to slide the chassis rails along the slide rails
until the mounting brackets are flush with the rack posts.
6. Use screws (user-supplied) to attach the mounting brackets to the rack, as shown in Figure 18.
To secure the switch in the rack, make sure the front ends of the slide rails reach out of the
chassis rails.
